mpnovslnsnrm GAS-LAMPS;

1*) Schedule referred to in these m Patent and ag part or the m.

York','have invented-an Improved Gas-Lamp; and I I .do hereby declare that the following is a full and exact description thereof, reference, being-had to the aceor'n'panying drawing t'orlning'a part of this specification, and to the letters of referencemarked thereon.

The object of my invention is to construct a gaslamp in such a manner that the gas generated from gasoline-may be utilized and consumed for illuminating purposes in a perfectly safe and economical manner, andthat the', lamp may be filled-with the material vfrom which the 'gas-Zis madewithout danger of expl0.-'-

sion'.

. Thematnrc ofmy invention consists, first, incoii 'ltfucting a chamber-for the material fromswhich the pis to be generated, through which chamber a tube s in a verticaldirection down through'the said. chamber into another ,chamberfi'or narrow space di'- rectly under the chamber. The dividing partition be-,

' tween these two chambers is made of non conducti'ng" material, so as to prevent any heat communicating into thegasoline-chamber. At the oppositeend ot the small space before inentionediis another tube which passes from the said spac'cnpwardto near the. top of the gasoline-chamber, which forms a communication from "the outer'atmosphere into the saidchambcr.

It further consistsin the combinationantler-range mcut of the valve which closes the orifice or opcning through which the lamp is filled with levers-and an' other valve that closes the upper end' of the gas-pipe. i To enable others skilled in the art to make and use myfinvention, Iwill-proceed more particularly to.de-"

scribeits construction-and operation.

Figure .1 represents an elevation of my improved gas-lamp, the hack being removed to showthe interior arrangement. v Figure 2 represents a transverse vertical section of .the' same, taken through the line X X in fig. 3.

Figure 3 shows a plan view of the lamp.

Letters of like name and kind indicate like parts in eachof the figures.

. A, in all the figures, represents the main oil-chamher, which-I makeof sheet metal, rectangnlarin form,

and of any suitable dimensions.

Upon the rear side of the main chamber A is an additional or auxiliary chamber, B, made in the form of a crescent, and located so as to come,. at .a proper distance, directly over the gas-jet and burner O, which burner is connected with rhegas-pipe 1),the latter of which extends upward and some distance into the main chamber A.

At the topof said pipe D is located and operated a valve' E, which-fits and closes tightly over the mouth ofthe saidpipe. i 'Tothis valveE are connected levers which also connect withanother valve, F, located upon the outer surface of the" auxiliary chamber B'which closes the opening through which the chambers are filled. The object and purpose of these valves is that the valve 1* is always closed, so as to retain the gas material-.\vitl1in the chamber, and is not designed to be opened except. when the chamber is being filled,

. Whn the valve-F is opened'through the medium of.

thelevers the valve E isclosed, so that, as will be (ab-'- served, theflow of gas is cut oli' from the burner, and .all d'angerof an explosion avoided.

G=represents apip'e or'tubepassiugfrorn the outer atmosphere down through the clntmberA into a nar-.

directly underneath the said chalnro'w space,- H, her A. a

l Atthe opposite side of this chamber is another pipe or tube, 1, that passes upward intothe'oil-chamber, so that a communication is made with the outer atmos-. 'phere and the oil-chamber.

J is a partition between the oil-chamber and the space H, made of any material which is anon-condoctor of heat, such as wood,zinc, plaster, or other well-known substance,'so that the heat from the burn-. er shall not come-so directly to the oil-chamber.

K K are bunches or hanks ofany fibrous material to hold'th'e gas material by absorption, so as to facilitate the 'generati'ng'of gas.

L represents a spring-hanger, by which the "lamp may be suspended and-elevated and lowered, for convenience in filling.

The flame from the bnrne'r'will gently heat the air as it passe's'through the tube and space H,which greatly fitcilitatcs the generatingof gas.

Having thus described my invention,

, -\Vliat I claim as new, and desire to secure by Letters Patent of the United States, is

1. The none0nduct-ingpartition J incombination I; with the space H ,.snhstantially as and for the purposes set forth.

2, Thearrangelnent of the valves E and l with the pipe D and chamber and described.

3. .The'pipe's G and I, for the-purpose of admitting air into the oil-chamber, in combination with the heating space H, substantially as shown and described.
